leading to high reactivity and excellent enantioselective control. Compared to the conventional methods, the reaction itself features alkenes as easily prepared starting materials, mild and operationally simple reaction conditions, and insensitivities to air and water. Moreover, this method allows for broad alkene substrate scope, excellent regio- and enantioselectivities, scalabilities and a wide array

A general, intramolecular cycloisomerization of unactivated olefins with pendant N-, O-, and C- nucleophiles is reported. The reaction proceeds under mild conditions, yielding a number of different heterocycles including, but not limited to, pyrrolidines, piperidines, oxazolidinones, and lactones. Use of both a benzothiazinoquinoxaline as organophotocatalyst and a Co-salen catalyst obviates the need
报道了未活化烯烃与侧链N -、 O - 和C - 亲核试剂的一般分子内环异构化。该反应在温和条件下进行,产生许多不同的杂环,包括但不限于吡咯烷、哌啶、恶唑烷酮和内酯。使用苯并噻嗪喹喔啉作为有机光催化剂和Co-salen催化剂消除了对化学计量氧化剂或还原剂的需要。
